Stetsonia Coryne | Argentine Toothpick Cactus
Stetsonia coryne, the only species of the genus Stetsonia, is a large, massive, tree-like columnar cactus that grows to a height of 3-10 m tall and is one of the most striking features of hot desert regions in Argentina. Miles Anderson 1998 commented that, once large, this species is cold hardy in areas where freezing is mild and brief. It is said to branch more densely and grow “as wide as it is tall” if allowed to experience intense sun and frost while in the ground. Can handle brief periods of below freezing. In outline, the plants resemble somewhat the many-branched Polaskia chichipe.
It is among the most famous cacti for the fiercely spines that cover the trunk and should prove an interesting and eye-catching plant for the specialist collector and for those wanting a somewhat different plant.
